Just my opinion but the generic term "Super" most commonly refers to a double similar gene co-dom only (e.g. Super Pastel not Spider or Pinstripe for example) so by implication, a Super Super would be a quad gene co-dom such as the Super Pewter (also produced by Mike Wilbanks in 2009 as well as Doug Matuszak in 2008 BTW). As for recessives, whilst I agree that a visual is a homozygous animal with similar genes from each parent, a Pied is not referred to as a Super het Pied is it just as a Pastel is not referred to as a het Super Pastel?
As for breeding Supers, I believe the common perception is that a Super x Normal = 100% visual morph offspring. This would therefore knock the recessive Super theory on the head too?
I suspect a lot of the more common Supers would produce varying shades of white snake (Super Lesser/Mojave/Butter/Russo/Fire combos etc) irrespective of what they are combined with but I'd be more interested to see a Super Pastel Super Enchi, Power Ball/Super Cinny/Black Pastel x something other than Super Pastel and Super Phantom/Mystic x anything!
Once again, this is just my opinion, this is a forum where views, opinions and experiences are shared and we're all entitled to have one before anyone starts bashing me!
